Masterbatch of Functional Chain Extender for rigid and flexible PET, it is suitable to improve rigidity and restore the Molecular Weight of recycled PET. It is also suitable to improve Intrinsic Viscosity. It is suitable in combination with AZ2311 or AT2608. The use in combination with SILMALINK AT2606 can give an increasing/restore of intrinsic viscosity of the recycled PET. Thermal stability of SILMALINK AT2607 is till 300 C therefore can use in all PET processes

Optional condition the branch reaction can be accelerated with SILMASTAB AT 1857 CAT.
